Introduction

=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

This program will find the number of diagonals in a shape.  You just have to 
type in the number of sides the shape has.  Like if you wanted a square.  You
 enter in the number "4", cause that's how many sides it has, and then you 
hit enter, and it will tell you that there are "2" diagonals in a square  =)

All below commands are for TI-81:

Note:  -->  Equals the "STO-->" Button.  This button can be found on a T-81 
right above the Off/On Button.  

Note:  You don't have to type in the ":"s, they're already there, I just 
wanted to make this look just like the calculator.

Note:  The "Disp" function can be found by hitting "PRGM" and then hit the
right arrow key once.

Note:  The "Input" function can be found by hitting "PRGM", then hit the
right arrow key once, then hit two.

Note:  The "End" function can be found by hitting "PRGM" and then hitting "7"
